# GA3: Stage 2, convolutional Model Make conv blocks: 2 layers w 32 filters + 2 layers 2 16 filters Window size 24h: ![](https://i.imgur.com/z5IvqyC.png) "Current pollution" baseline: train mae = 29.565208 validation mae = 31.122208 => Lower LR to 0.005 => Swap StandardScaler to MinMaxScaler ![](https://i.imgur.com/j8gtyKA.png) More stable learning, but scores remain the same
